MODE FOR INVENTION

Hereinafter, the exemplary embodiments of a security system for an external data storage apparatus and a control method thereof according to the present invention will be described in greater detail with reference to the accompanying drawings.

-   -   FIG. 1 is a block diagram illustrating a security system for an         external data storage apparatus according to the present         invention.         Referring to FIG. 1, the security system for an external data         storage apparatus according to the present invention comprises:         a data storage 10, in which data is stored; an external case 20,         in which the data storage is held; a key input unit 30, which         outputs an input signal through a key pad operated by a user; a         control circuit 40, which controls data input and output of the         data storage; a display 50; a battery 60, which supplies power;         and a high-speed serial bus 70, which sends the data to the data         storage.

The data storage 10 includes a hard disc or a memory disc, and stores data input from a personal computer or another storage medium (hereinafter, referred to as “data terminal”) through which the data can be input and output, and outputs the data at the request of the data terminal, which can input and output the data into and from the data storage 10.

The external case 20 is used as an ordinary housing, and includes the data storage 10, the control circuit 40 and the battery 60 are held therein. The key input unit 30, which is electrically connected with the data storage 10, and the display 50 are provided on an outer surface of the external case 20.

The key input unit 30 is an input device that is combined with character or numeral keys, for example, numeral keys consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0, and outputs an electrical signal set for each key according to the operation of a user. Thus, the key input unit 30 outputs various input signals according to the operation of a user, for instance a mode change signal for setting or registering a first identification (ID) of the user and a security mode selection setting signal for preventing the data stored in the data storage 10 from being read and written when directly mounted on the data terminal.

Here, the key input unit 30 can select a drive mode of the data storage 10 when the data terminal requests the data stored in the data storage 10, which will be described using a flow chart of FIG. 2.

The control circuit 40 comprises: a high-speed serial bus controller 41, which controls input and output of the data transmitted/received through the high-speed serial bus 70; a security processor 42, which compares a key input signal and an ID to thereby permit the data to be input into and output from the data storage 10; a data storage controller 43, which controls the data storage 10 to be driven; and a memory 44, in which set IDs are stored.

The memory 44 registers and manages the IDs input from the key input unit 30, and boot and file system information sectors of the data storage 10, and thus registers a new ID input according to an ID change mode selection signal of the key input unit 30.

The high-speed serial bus controller 41 detects the state of the high-speed serial bus 70 to determine whether or not the external data storage apparatus is connected with the data terminal 80. When detecting disconnection, the high-speed serial bus controller 41 outputs a disconnection detection signal to the security processor 42, and intercepts the data input and output of the data storage 10 on the basis of a control signal of the security processor 42.

The security processor 42 compares the ID input through the key input unit 30 with the previously registered ID, and determines whether or not the two IDs are equal to each other. Here, the security processor 42 determines whether the input of the key input unit 30 is an ID input mode or an ID change mode. In the case of the ID input mode, the security processor 42 compares the ID input through the key input unit 30 with the set ID stored in the memory 44, and outputs an ID equality signal.

At this time, as described above, the security processor 42 outputs a drive instruction signal of the data storage 10 to the data storage controller 43 according to the mode selection signal of the data storage 10 which is selected by the key input unit 30. When the IDs are equal to each other, the security processor 42 outputs a connection state detection signal of the high-speed serial bus 70 to the high-speed serial bus controller 41.

Thus, if a file system record mode (hereinafter, referred to as “first mode”) of the data storage 10 is selected by the key input unit 30, a first mode selection signal is applied to the data storage controller 43 so as to record the file system information of the data storage 10. Further, if a storage sector re-arrangement mode (hereinafter, referred to as “second mode”) of the data storage 10 is selected by the key input unit 30, a second mode selection signal is output so as to rearrange storage sectors of the data storage 10.

When the ID equality signal is output from the security processor 42, the data storage controller 43 normally drives the data storage 10 so as to enable the data terminal 80 to read and write the data stored in the data storage 10 through the high-speed serial bus 70, because normal file system information is recorded in the boot and file system information sectors of the data storage 10.

Afterwards, when the disconnection detecting signal detecting the disconnected state of the data terminal 80 is applied from the high-speed serial bus controller 41, the data storage controller 43 controls any data terminal to input a correct ID according to the first or second mode selection signal set by the security processor 42, such that the data stored in the data storage 10 does not leak out through a terminal other than the data terminal, which is authorized to access the data storage 10.

In other words, in order for an unauthorized data terminal 80, on which only the data storage 10 is separated and mounted, not to read out the data stored in the data storage 10, the external data storage apparatus prevents the data stored in the data storage 10 from leaking out using the first and second modes.

Thus, when the first mode is selected, the data storage controller 43 records wrong information in the boot and file system information sectors of the data storage 10 in a format, which cannot be read out of the boot and file system information sectors by the data terminal (for example, the Windows based computer), thereby preventing only the data storage 10 from being separated and connected to the other terminal without inputting the ID.

Further, when the second mode is selected, the data storage controller 43 re-arranges the storage sectors of the data storage 10 in real time, outputs location signals of the storage sectors, and enables the data terminal 80 normally inputting the equal ID to be connected to the data storage 10.

More specifically, when the data storage 10 is normally driven, the data storage controller 43 first re-arranges the storage sectors, and outputs the location signals of the storage sectors. Thus, the data terminal 80 recognizes locations of the storage sectors re-arranged by the data storage controller 43 to read in the corresponding sector. This is performed by the data storage controller 43 in real time. Thus, in the case in which only the data storage 10 is separated and connected directly to the data terminal 80, the data storage controller 43 does not inform the locations of the changed storage sectors, so that the data cannot be read out of and written in the data storage 10.

The display 50 outputs messages sent from the high-speed serial bus controller 41, the security processor 42, the data storage controller 43, and the memory 44, as well as the current state connected with the high-speed serial bus 70, the input mode or the change mode of the ID, and the information on which one of the first and second modes is selected.

The battery 60 supplies power capable of independently driving the data storage 10 and the control circuit 40 without separately supplying external power. In the case in which the data terminal is connected through the high-speed serial bus 70, the battery 60 can be charged using power supplied from the data terminal 80.

The high-speed serial bus 70 transmits/receives the data between the external data storage apparatus and the data terminal, and preferably includes universal serial bus (USB), IEEE1394, and serial advanced technology attachment (SATA).

The operation of the security system for the external data storage apparatus according to the present invention, which includes the configuration as described above, will be described in detail using a flow chart of FIG. 2.

FIG. 2 is a flow chart for explaining a method of controlling an external data storage apparatus according to the present invention.

Referring to FIG. 2, the method of controlling an external data storage apparatus according to the present invention comprises: step S101 of detecting the connection between the external data storage apparatus and the data terminal 80, step S102 of maintaining the key input unit 30 in a standby state, step S103 of maintaining the key input unit 30 in a locked state when the data terminal 80 is not connected, step S104 of determining which one of the input and reset modes of the ID is selected in the standby state of the key input unit, step S108 of comparing the input ID and the set ID when the input mode of the ID is selected in step S104, steps S106 and S111 of re-registering the input ID when the reset mode of the ID is selected in step S104, and steps S201 through S206 of driving the data storage 10 when the IDs are equal to each other in step S108.

Here, in step S101, the control circuit 40 determines whether or not a user connects the high-speed serial bus 70 to the input port of the data terminal. Thus, when the high-speed serial bus 70 is connected to the data terminal 80, the control circuit 40 turns on the key input unit 30, and converts the key input unit 30 in a standby state.

In step S102, the key input unit 30 is turned on by the power output from the battery 60 according to control of the control circuit 40, and enters the standby state for driving according to an input signal from the built-in keyboard having a plurality of keys.

In step S103, the control circuit 40 does not detect that the high-speed serial bus 70 is connected to the data terminal. This state is an off state in which the power output from the battery 60 is not applied.

In step S104, the user selects the input or reset mode of the ID using the keyboard of the key input unit 30. Thus, the control circuit 40 determines whether or not a mode selection signal applied by the key input unit 30 is based on the input or reset mode of the ID.

In step S111, when a mode selection signal is based on the reset mode of the ID, the control circuit 40 overwrites an input signal input subsequently on top of the preset ID of the memory 44, thereby re-registering the ID.

In step S108, when a mode selection signal applied by the key input unit 30 is based on the input mode of the ID, the control circuit 40 compares an input signal input subsequently with a set ID stored in the memory 44, thereby determining whether or not the data terminal is authorized to provide access to the data storage 10.

Preferably, the display 50 displays the mode selection of the key input unit 30, as well as a security mode of the data storage 10 and an instruction selected and input through the key input unit 30, both of which will be described below, according to the control of the control circuit 40.

In steps S201 through S206, since the security processor 42 of the control circuit 40 outputs an ID equality signal when the IDs are equal to each other in step S108, the data storage controller 43 authorizes the data terminal 80 to access the data storage so as to enable the data to be read out of and written in the data storage.

In addition, in the steps of driving the data storage 10, the data storage 10 is controlled using the first and second security modes for detecting the disconnection from the data terminal to prevent the data stored in the data storage 10 from leaking out.

More specifically, the external data storage apparatus is generally used in a manner such that the data storage 10 is held in the housing and is connected to the input port (for example, USB) of the data terminal through the high-speed serial bus 70 as described above. However, this external data storage apparatus may be used not only by connecting the data terminal with the high-speed serial bus 70, but also by separating only the data storage 10 from the external data storage apparatus and then directly connecting the separated data storage to hardware of the data terminal. Thus, the present invention sets the ID in order to authorize the data terminal, which is used by an authorized user when connected with the data terminal, to access the data storage, and simultaneously resets the storage sectors or file system information of the data storage 10 in order to prevent an unauthorized user from separating only the data storage 10 and directly mounting the separated data storage on the data terminal 80 when in use, so that it enables the unauthorized user to prevent the data from leaking out.

As for steps S201 through S206 of driving the data storage, when the IDs are equal to each other in step S108, the security processor 42 reads out a security mode set for the memory 44 to determine whether the security mode is the first mode (the file system record mode) or the second mode (the storage sector re-arrangement mode) (security mode selecting step S201). When the first mode is selected in the step of selecting the security mode, the file system information of the data storage 10 is recorded as normal information, and then the data storage is normally driven (first mode normal driving step S202). It is determined whether or not the state connected with the data terminal is released (first mode disconnection detecting step S203). When the state connected with the data terminal is released, the file system information of the data storage 10 is recorded as arbitrary unrecognizable information, and thereby the data storage 10 is intercepted (file system information recording step S204). When the second mode is selected, the data storage is normally driven (second mode normal driving step S205). The storage sectors of the data storage 10 are re-arranged in real time during the normal driving of the data storage (storage sector re-arranging step S206).

In the security mode selecting step S201, the security processor 42 determines which one of the first mode and the second mode is selected according to the mode selection signal input through the key input unit 30 or the mode selection information stored in and set for the memory 44. In the first mode normal driving step S202, when the security processor 42 outputs the first mode selection signal in the security mode selecting step S201, the data storage controller 43 records normal information, for instance data having a format which a Windows based computer can recognize, in the boot and file system information sectors of the data storage 10 so as to enable the data terminal to recognize the data stored in the data storage 10, thereby authorizing the data terminal to provide access to the data storage 10.

In the first mode disconnection detecting step, when an ID equality signal of the security processor 42 is applied, the high-speed serial bus controller 41 detects the state in which the high-speed serial bus 70 is connected with the data terminal, and outputs the detected signal to the data storage controller 43. Thus, the data storage controller 43 performs the following file system information recording step when the high-speed serial bus controller 41 detects that the data terminal 80 is disconnected from the high-speed serial bus 70.

In the file system information recording step S204, when the disconnection detecting signal of the high-speed serial bus controller 41, which detects the disconnection of the high-speed serial bus 70, is applied, the data storage controller 43 records arbitrary file information, which cannot be recognized from the boot and file system information sectors of the data storage 10 by the data terminal 80, and thus the data terminal 80 is abnormally connected to the data storage 10 without inputting an correct ID, so that the data is prevented from leaking out to the unauthorized data terminal 80. Although any unauthorized user tries to mount only the data storage 10on his/her own data terminal 80 and make use of the data storage 10 without inputting the ID, the data terminal 80 of the unauthorized user cannot recognize the data stored in the data storage 10 due to the wrong file information recorded in the file system information sector.

In addition, in the second mode normal driving step S205, when the second mode selection signal and the ID equality signal of the security processor 42 is applied in the security mode selecting step, the data is input and output between the data storage 10 and the data terminal according to the control of the data storage controller 43.

Here, like the first mode normal driving step S202, in the second mode normal driving step S205, the data stored in the data storage 10 can be recognized by the data terminal by recording normal information in the boot and file system information sectors of the data storage 10, or the access of the data terminal can be authorized by the connection of the high-speed serial bus 70 without recording the file system information of the data storage 10. This can be variously modified according to the application of the user.

In the storage sector re-arranging step S206, when the second mode normal driving step S205 is initiated, the data storage controller 43 re-arranges the storage sectors of the data storage 10 in real time, sends the changed locations of the storage sectors to the data terminal, and enables the data terminal, which inputs the equal ID, to read and write the data stored in the data storage 10.

More specifically, in order to read and write the data stored in the data storage 10, the sectors of the data storage 10 must be designated. Hence, the data terminal 80 must receive the location signals of the changed sectors, which the data storage controller 43 re-arranges the storage sectors in real time and then sends, to recognize the locations of the changed sectors. Thereby, the data terminal 80 can read and write the data stored in the data storage 10.

For example, however, in the storage sector re-arranging step S206, when only the data storage 10 is separated and connected directly to the interior of the data terminal 80, the data storage controller 43 is disconnected from the data storage 10, and thus does not inform the re-arranged locations of the storage sectors. As such, the data terminal 80, which is connected in this abnormal method, cannot read or write the data stored in the data storage 10.
